How many blowholes does a Baleen Whale have?

The Baleen Whale has 2 blowholes that serve as its nostrils and are situated at the top of its head. The blows of the Baleen Whale are considered to be bushier than those created by toothed whales who typically only have a single blowhole. Baleen Whales can also expand their throat to gulp large amounts of seawater.

What does a Baleen Whale eat?

The Baleen Whale typically eats krill, fish, zooplankton, phytoplankton, and algae. The Baleen Whale feeds by filtering or straining food from the water they consume. The Baleen Whale has baleen plates which they use to push water out while trapping their food inside for them to swallow.

How did Baleen Whales evolve?

It is believed that Baleen Whales evolved from a common ancestor who lived more than 23 to 25 million years ago. Unfortunately, the common ancestor has not been discovered, but probably lived within the Oligocene period. It is also believed that the earliest ancestor of the toothed whale lived during this time.

What are the three groups of organisms that are considered cetaceans?

The 3 groups of organisms that are considered cetaceans are whales, dolphins and porpoises. The 3 groups are made of 89 species in total. The cetacean order is further divided into 2 groups: toothed whales (odontocetes) that includes over 73 species and baleen whales (mysticetes) that is made up of 11 species.

What do cetaceans eat?

All species of cetaceans are carnivores. A cetaceans’ diet depends on the species, but most cetaceans feed on mostly fish, and marine invertebrates. Some like the killer whale, feed on large mammals and birds like penguins or seals. Baleen whales usually eat mollusks, copepods, krill, small fish, and squid.

Where do cetaceans live?

Cetaceans can be found in all climates and all oceans of the world ranging from the coldest waters to tropical waters. Some species live only in specific areas, like the southern right whale dolphin and hourglass dolphin that only inhabit the Antarctic Ocean. Some species of whales migrate between seasonal habitats like the gray whale.

What do marine animals need to survive?

Factors that marine animals need to survive include bioluminescence which is when animals make their own light and helps them communicate and scare predators. Constant light, pressure, temperature, and food are factors needed to remain stable and help marine animals evolve to survive. Marine animals that live within the deep sea can withstand the cold.

Why do we need to protect marine life?

Humans need to protect marine life because our actions and lifestyles have a direct impact on the ocean. We need to protect marine life and provide a safe and healthy environment that is not impacted by overfishing, climate change, pollution, habitat destruction, invasive species, and other forms of human exploitation.
